SilverStone Technology 4U Rackmount Server Chassis with 3 X 5.25 Front Bays with CEB/ATX/mATX/Mitx Support RM400 Cases SST-RM400

The double-packed box more than withstood the rigors of UPS. There was no damage to the case. The case was more than I expected. The pictures (here and elsewhere) don't do it justice. It is roomy, well built, beefy (not light!) and well finished. The dust filters are not magnetic, but snap in; they should be something that you are careful with. The case isn't a deep monster, but has enough room for a good build. I'm using SAS drives and while the drive connectors extend into the "motherboard area" it hasn't been a problem. That said - I have four 6TB drives. Depending on the number of drives you have and the amount of drive cooling you want, YMMV. I haven't had a chance to resilver an array so I don't know what internal temperatures would be like. But, so far, so good. It will probably take me a couple of weeks to become aquanited with the nuances of the case. The "handles" on the case are sturdy and more than support the weight of the case. I haven't installed rails as my rack hasn't been built yet. The case handles remind me a bit of the old APC UPS units (that kind of sturdy). The case connectors were long enough for my build, but I could see issues with others - depending on motherboard, components and cable routing. In my case everything went together well. There have been complaints about not being able to remove the drive trays or moving parts around but that doesn't seem to be a problem - it may take a few seconds to figure out what to unscrew but it can be done. I don't know if any parts of the clone cases will fit, but I'd be game to try. Overall a nice case. Yeah it was expensive, but I think it was worth it. AND it was in stock. The only nit to pick is the use of the small screws (use a magnetic tipped screwdriver!). I have enough parts to build a second server. If I had the same requirements, I wouldn't hesitate to use the same case. *** UPDATE *** I had to replace hard drives as my sas drive went to the bit dumpster in the sky. I purchased some ironwolf sata drives and found that i can only use two mounting screws to secure the drives. I don't think it is a fault ot teh case, but having deeper hard drive bays would allow for secure mounting of hard drives. And a curse on Seagate for deciding to omit screw holes. So if secure hard drives are your thing... you might want to take that into consideration...

bought this case to build a media server for running Resolume video processing software in a theater environment. Very solid case. heavy gauge metal, good quality rack mount ears and construction. mounted in a road case and won't worry about it breaking. and great that is it 4U so doesn't take a lot of rack space. Lots of room in the case for mounting any size motherboard that you'd way, I used an full size ATX with a 850W power supply. I didn't mount any 2.5 or 3.5 drives so can't comment on the drive mounting cages since I was using M2 drives The stock fans are single speed, very loud fans, didn't even plan on using them. I replaced them with Arctic PWM high quality 80 and 120mm fans which should last the life of the server. Because this is only 4u, you will need to make sure your CPU cooler will fit in the case. I used a Noctua NH-C14S which fit when mounted in the low-profile single fan config. Or just get a non-overclocking CPU and use the stock fan which would fit with no problems. So nice, I bought a second one to build an identical media server for our other location.

This is specifically for the SST-RM4400. I wasn’t sure about the depth on this case at 18.5". My open-frame Navepoint 12U rack is 18" deep, which makes this case (and many others) difficult for those with shallow racks. The RM-4400 includes a front-folding vanity door, which protects front of the case and provides a very clean look. It's initially what attracted me to the chassis. However, I discovered that it adds roughly a full 1" of depth to an already long case intended to fit into a 18" deep rack. After I took delivery, I discovered that the front folding cover is removable, which would provide me the ~1" of additional clearance I was looking for. The case is pre-drilled to accommodate different versions of Silverstone cases and it so happens that the handles can be moved back ~1" to provide the extra room needed to clear the back of my rack. Silverstone makes several variants of the RM-series cases, especially the RM41-H08. However, the RM41 chassis includes a 5-bay hotswap drive where the 5.25" bay sits in the RM4400 case. The RM4400 case is exactly $135 cheaper than the RM41-H08, which is exactly the cost of their 5-bay hotswap drive purchased separately. The RM41 includes a 5-bay hotswap drive but one less 4-bay 3.5" internal rack for HDDs. If you’ve seen this, then buy the RM4400 and pick up any 5-bay hotswap that you desire. If you do that, then technically the RM4400 can accommodate up to 13 3.5" HDDs with a 5-bay hotswap drive to replace the 5.25" bay. That’s impressive. This case will fit in a shallow 18" deep open rack if you can extend your rack ~1" off the back wall to allow for cables to clear. I also swapped the original power cable to a right angle 16awg cable from Monoprice (via Amazon). Removing the front cover of the RM4400 makes this chassis exactly the same dimensions as the RM41-H08: 430mm (W) x 176mm (H) x 446mm (D) 16.93" (W) x 6.93" (H) x 17.56" (D) The RM4400 chassis accommodates a single 120mm fan and 3 80mm fans for HDD cooling and rear case venting. I got rid of the OEM fans and swapped them for Arctic and Noctua fans.
